FIELD OF INVENTION

The present invention relates to an improved coupling apparatus.

BACKGROUND

Traditional methods of construction of residential buildings has historically used bricks, breeze blocks and/or infilled timber frames to provide structural strength. These buildings then require the addition of insulation to improve the thermal efficiency of the building. However, in 1947 development began on Structural Insulated Panels (SIPs). A SIP is a composite building material consisting of an insulating layer of rigid core sandwiched between two layers of structural board (OSB).

Use of SIPs has become an increasingly popular method of construction, particularly of residential buildings, replacing the traditional construction methods due to the speed and ease of build, superior insulation performance, and structural strength. However, connecting one SIP to an adjacent abutting SIP can be problematic as it involves applying adhesive and/or screwing or nailing the panels to the abutting or adjoining counterparts. One common practice uses a spline. The spline bridges the join between two SIPS by being inserted into two preformed channels that underlie the surface OSB in a SIP along the edge of the join between two SIPs. When in place, an installer can then use fastening means across the join line where two SIPs abut to secure the panels.

Problems arise when implementing this method in practice. Firstly, where two SIPs abut, each SIP must be specifically adapted to receive the spline adding to manufacturing costs. Secondly, fitting the spline on site can be precarious slowing the overall progress of the build.

SUMMARY

It is an object of the present invention to obviate or mitigate the need for extra materials, i.e. splines, when coupling adjacent abutting SIPs to one another; and improve the efficiency by which SIPs can be abutted in building panels with multiple SIP panels.
